SPECIFICATION forming part of Letters repent No. 288,353, date ive-:lernter 1s, lese.

Appntation sled retrnary 26, 1883. (No model.)

Be it known that I, SAMUEL D. MADDIN, of St. Paul, Ramsey county, Minnesota, have invented certainImprovements `in Harvesters,

f illustrate my improvements.`

of which thefollowing is a specication. y

My invention `has for its object to improve the frame and operating devices of a harvest-` ing-machine, so as to facilitate the manipula-` tion of the same and secure better results.

In the drawings, Figure l is a perspective viewof sufficient of a harvestingfmachine to Fig. 2 is a sectional elevatiomand Fig. 3 is a detached view I of the frame-adjusting appliances.

The harvester illustrated in the drawing is similar in its general construction to that patented to meNovember 9, 1880. y

A is the axle; B` B, the supporting-wheels.

`F G is the frame, consisting of two parts, the

part Gbeing integral with a sleeve, G', inclosing and swinging on the axle, and the part F,

which carries the cutter-bar E, being pivoted atmto the part G, so that either side of the cutter-frame can be raised, as in the machine described inthe aforesaid patent. The cutter is driven from a crank-wheel, C, by means of a pitman, a, and crankshaft II, `asin the aforesaid patented machine.`

In the machine described in the aforesaid patent the cutter-bar frame could be tilted by means of a lever, 'which was fixed to hold the frame in any desired position, there being no yield or accommodation other` than could be secured bythe iiexibility of the parts. To obviate this Objectionand enable the cutterbar to float,V as it were, freely upon the ground, and pass with ease over obstructions, I interpose one or more springs between thefhoisting-lever F and the frame, which springtends to keep the lever back in its place `near thedriver, and prevents it from shaking loosely as the machine is j Olted, and also tends to turn the bar and its segmental arms, so as to create an` upward draft upon'the frame F, thus permitting the latter to rise easily when `it meets with any obstruction. At the same time, by

manipulating the lever F and its pawls and bars, as described in the aforesaid patent, either side ofthe frame may be raised or lowered.

The arrangement of springs is shown best in Fig. 3, in which zo is inthe segment-shaft, to

which is attached the segment e and notched collar On the shaft turns freely a notched collar7 u', ,segment e2, and the lever F', the pawls Ao of which maybe brought into the notch of either collar. A spring, M, is interposed between the segment e2 and collar u', i

and a spring, M', between the segment e and a ratchet-wheel, t, which turns freely on the shaft, and `is held by a pawl, s, so as to maintain any tension applied lto the spring.k The springs 'tend to raise the segments, lift the frame, and keep the lever from shaking,

To overcome the preponderance of weight resulting` from the frame F G being entirely at one side of the axle, yI extend from the frameG, or the sleeveG thereof', to the rear u arms d, to which I pivot the -ends of arms J,

extending downward from the pole L, the lat lter projecting tothe rear and supporting the drivers seat D, so that the weight of the pole and driver counterbalances that ofthe frame, and there is a tendencyto lift the cutter-bar without any downward pressure on the horses neck.

`In a direct-draft mower, where the bar is in front of the drive-wheels, it has been custornary to placethe lead-wheels 4. outside of the y shoe, which, being between thewheel and the cut. As this rod is` fastened to the journal on which 4the wheel turns, it will rise and fall with` the wheel as the `latter is set higher or lower. Foot-levers J', pivoted to the sleeve G', are connected at the outer end tothe swinging frame, so that the driverby pressingwith his foot on either lever, can raise thatend of thel bar, or he mayraise the entire bar by pressl ing on both levers.

- but will yield so that the bar will rise and fall over-uneven ground. y

I also use a guide- -near the center from thesideprior to being I do not abandon or dedicate tothe public` any patentable features set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of any patent that may be granted upon this appli- 5 cation or in other applications for Letters Pat- `ent that I may make.

I therefore claim- 1. The combination, in a harvester, of a pole havingva pivoted bearing upon a projecting 1o portion of the frame G at the rear of and below the journals, and a frame connected to the axle, extending to the front and supporting the cutter-bar, substantially as set forth.

. 2. The combination of the axle A, arms or 15 rear extension, d, frame F G, extending to the front, and pole L, having its bearings on the rmls1 d below the axle, substantially as set ort 3. A spring interposed between the operatl and connected with the latter, so as to exert an upward draft thereon, substantially as set forth 4. The lead-Wheel 4, arranged inside the shoe and in front of the cutter-bar, in combination with guide-bar b, connected with the 25- sides of the center thereof, substantially as set forth.

In testimony whereof I have signed my name to this specification inthe presence of two subscribin g witnesses.

SAMUEL D. MADDIN.
